Inquiry checklist
Concrete use or PCE synthesis route.
Required grade and performance objective.
Sample, trial or estimated order volume.
Country, port and packaging needs.
Buyer-oriented technical selection
Rheology modification in cement-, gypsum- and lime-based mortars.
Viscosity, dosage, cellulose-ether combination, sag resistance and workability target.
Hps is commonly evaluated with the intended hpmc/hemc grade rather than as an isolated ingredient.
Ask for the current grade specification and batch documentation. Review available company certificates, test evidence and supplier batch-report scope separately.
Calculate wet-basis and dry-basis moisture from sample weights.
